Sleever Bar with Adjustable Removable Nut for Steel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sleever bars used in structural steel alignment lack versatility in aligning and separating structural steel members efficiently, as they are limited in adjustable positioning and leverage during the alignment process.
Innovation Solution
An improved sleever bar design featuring a permanently attached fixed nut and an adjustable removable nut, allowing for precise alignment of structural steel members' holes and providing enhanced leverage for separation using an angled claw, enabling secure fastening with nuts and bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional sleever bar is used for aligning structural steel members, then the alignment function is provided, but the versatility and adjustable positioning capability are limited
Solution Approach 1:
The sleever bar is designed with dual functionality: a fixed nut for alignment and a removable nut for both alignment and separation operations. This multi-functionality allows a single tool to perform multiple tasks (aligning holes, securing members, and separating members) without requiring multiple specialized tools, thereby improving versatility while maintaining relatively simple device complexity
2Measurement precision
If a fixed positioning system is used on the sleever bar, then the device structure is simple, but the alignment precision and adjustability are insufficient
Solution Approach 1:
The sleever bar incorporates both fixed and movable elements: the fixed nut provides stable reference positioning, while the removable nut can be positioned at different locations along the bar using a simple retaining mechanism. This dynamic combination allows adjustment of the removable nut's position to achieve precise alignment for different hole configurations without requiring complex adjustment mechanisms
3Productivity
If leverage is increased for separating structural steel members, then the separation efficiency is improved, but the device complexity and potential damage risk increase
Solution Approach 1:
The removable nut serves as an intermediary tool for separation operations. By positioning the removable nut in a hole of one structural steel member and using the sleever bar as a lever, the nut mediates the force application between the sleever bar and the structural member. This allows controlled leverage to be applied through the nut's threads, providing efficient separation while distributing forces to minimize damage risk compared to direct lever application

AI summary
The improved sleever bar comprises a bar, a removable nut and a fixed nut. The fixed nut is permanently attached to the bar at a fixed position. The removable nut is attached to the bar such that the position of the removable nut is adjustable. In a first function of the improved sleever bar, the improved sleever bar aligns the first object with the second object such that the center axis of each of a first plurality of holes is aligned with the center axis of a hole selected from a second plurality of holes such that a nut and bolt selected from a plurality of nuts and bolts can be used to secure the first object to the second object. In a second function of the improved sleever bar, the improved sleever bar separates the first object from the second object.
